Sass darken and lighten functions replace with color.adjust in Visual Studio Code

How to replace Sass darken and lighten functions throughout the code with color.adjust in Visual Studio Code.

Sass color.adjust function is now replacing darken or lighten functions with the new Sass module system. However, making changes manually to all files can be very time-consuming. Here is how to make it faster for all files in Visual Studio Code.

Replacing darken or lighten with color.adjust automatically in all files

Use the following regular expressions:

• For darken function in the field Search use: darken\((.*),\s*(.*)\), and for field Replace use: color.adjust($1, $lightness: -$2).
• For lighten function in the field Search use: lighten\((.*),\s*(.*)\), and for field Replace use: color.adjust($1, $lightness: $2).

Example from Visual Studio code for darken case:

Notes

• Always verify the final results. The regular expression may not be able to catch all possible combinations from the source code. Upgrade Sass to the latest version and use Stylelint to validate the Sass code.
• You may get the compile error SassError: There is no module with the namespace “map”..

  Add the following line in all files that uses map functions:

  @use "sass:map";

• You may get the compile error SassError: There is no module with the namespace “color”..

  Add the following line in all files that uses color functions:

  @use "sass:color";

• You may get the compile error SassError: There is no module with the namespace “str”..

  Add the following line in all files that uses str functions:

  @use "sass:string";

  Also, all functions started from str. should be replaced with string. function.

• Adjust code for rgba function. Example:
  • Original value: rgba(color.adjust($action-danger, 5%), $lightness: 0.2).
  • After changes: color.adjust($action-danger, $lightness: 5%, $alpha: 0.2).
